Give any two similarities between human eye and a photographic camera?

The retina in the human
eye is similar to the photographic film in a camera. The pupil in the
human eye is similar to the aperture (opening) in a camera.

in a photographic camera,
the focal length of the lens is fixed and the distance of the image from
the lens changes when the position of the lens is changed. In the human
eye, the focal length of the eye lens is changed by the ciliary muscles
and the distance of the image from the eye lens is fixed.

The ciliary muscles adjust
the size (the curvature) of the eye lens. The refraction of light is responsible
for the working of the eye.
